The primary focus of our lab is to understand how changes in gene expression regulates cell fate transitions and function. Dysregulation of these processes, especially long-lasting epigenetic changes, are critical to many diseases. In particular, our laboratory focuses on how non-coding DNA elements act as “molecular switches” to causes changes in gene expression. We use different models to understand how non-coding DNA elements regulate which genes are on or off to regulate both normal cell functions but also disease. Currently my lab focuses on two models to address mechanistic questions.

1. Acute Myeloid Leukemia (AML). We focus on AML because it has a poor long-term survival even with high dose chemotherapy, illustrating the need for more effective, less toxic therapies. In AML, approximately 15% of patients have mutations within genes encoding the cohesin complex, which plays a critical role in allowing non-coding DNA elements to regulate gene expression. Most of our studies rely upon next-generation sequencing-based genome wide approaches, in addition to genomic editing to understand how cohesin mutations promote AML, with the goal being to develop more effective, less toxic therapies.
2. Hypertension.In many ways, hypertension represents one of the most widely studied human traits, because it is a critical mediator of cardiovascular disease. Genome wide association studies (GWAS) have identified thousands of single nucleotide polymorphisms (SNPs) which are associated with hypertension. Importantly, the overwhelming majority (>90%) do not reside within the coding region of genes. Our lab focuses on understanding whether these SNPs within noncoding regions of the genome can operate as molecular switches to alter gene expression and tries to define the mechanisms they use to regulate blood pressure. Our long-term goal is to translate this information into precision medicine approaches to best treat patients with hypertension.
